Africa is highly vulnerable to the influence of the climate. The continent contains many of the world’s least developed countries, who have limited capacity to mitigate against the impacts of extreme events. The continent is also highly dependent on rain-fed agriculture which is at the mercy of fluctuations in rainfall from season to season. Amongst the most vulnerable areas are the semi-arid regions of the Sahel and the Greater Horn of Africa; many of these regions also suffer from unstable security situations, and in the worst cases, drought and conflict can combine to trigger famine, as in Somalia in 2011-12.
Like the rest of the world, Africa is warming. 2019 was likely the third-warmest year on record for the continent, after 2010 and 2016. Over the last 30 years, the continent has been warming at a rate of 0.3 °C to 0.4 °C per decade, a similar rate to the global average for land areas. 2019 was an especially warm year in southern Africa, where parts of South Africa, Namibia and Angola had temperatures more than 2 °C above the 1981-2010 average.Continue reading
